I have a customer running a 2800 series, (i know its old but works fine)
In the URL Web content Filter we have email sites blocked Hotmail, Yahoo, MSN, Gmail and generally it works
BUT
If you go to the google.co.uk page and click gmail at the top of the screen it allows access to the mail gmail login page and you can login (dam)
However if you click on any of the other gmail links on that page such as "About Gmail" "Create new account" etc they are all blocked.
I dont understand it.
In the content filter i have blocked "gmail", "mail.google.com" "accounts.google" and even "https://mail.google.com/mail/"

So why is it letting them through to this page so they can login?
